Description

Technical Field

[0001] The present invention belongs to the field of mining equipment, and more specifically, relates to a device for draining and desludging water in sandstone fissures of a fully mechanized mining roof. Background Art

[0002] Nowadays, with the continuous deepening of coal seam mining, modern mining equipment is being used to mine thick coal seams. Factors such as mining depth, post-mining, and mining techniques, roof rock properties, working face inclination, mining speed, and working face span all influence the development mechanism and height of water-conducting fracture zones in the roof. Because the Shanxi Formation coal-bearing strata are overlain by extremely thick sandstone and alkaline rock aquifers, factors such as the height of the water-conducting fracture zone, mining disturbance, and roof surrounding rock migration are all crucial for preventing and controlling sandstone fissure water.

[0003] Currently, methods for managing water in sandstone roof fissures rely solely on pre-mining geophysical exploration and drilling drainage. However, research into the migration of roof water during mining and the development of water-conducting fracture zones in large-span, deep-burial coal faces has been neglected. Currently, sandstone fissure water hazards often result in delayed water inrush in the underlying goaf, with no preventative monitoring measures in place. The accumulation of sediment during drilling drainage inconveniences water transportation, resulting in low efficiency and a high workload and difficulty for maintenance, significantly increasing maintenance costs. Summary of the Invention
